Nanomaterials promise to revolutionize healthcare and medicine by offering a new generation of diagnostic and therapeutic tools.Both organic and inorganic nanoparticles have been extensively explored as drug delivery vehicles to develop highly selective and effective therapeutics and diagnostics.The incorporation of inorganic nanoparticles into organic assemblies can endow the system with new advanced functionalities (e.g.plasmonic and magnetic properties), while preserving the well-established properties of the organic components.
